Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs.
Louping-ill is a tick-transmitted disease whose occurrence is closely related to the distribution of the primary vector, the sheep tick Ixodes ricinus. It also causes disease in red grouse , and can affect humans. [ 1 ]
In humans (specifically gastrodiscoidiasis) symptoms include diarrhoea, fever, abdominal pain, colic, and an increased mucus production. Large amounts of eggs can cause tissue reactions in the heart or mesenteric lymphatics, which may lead to death. Mortality among native Assamese children is attributed to this infection.
Four species infect humans: B. abortus, B. canis, B. melitensis, and B. suis. B. abortus is less virulent than B. melitensis and is primarily a disease of cattle. B. canis affects dogs. B. melitensis is the most virulent and invasive species; it usually infects goats and occasionally sheep. B. suis is of intermediate virulence and chiefly ...
Orf is a zoonotic disease, meaning humans can contract this disorder through direct contact with infected sheep and goats or with fomites carrying the orf virus. [6] It causes a purulent-appearing papule locally and generally no systemic symptoms.
This parasite is responsible for anemia, oedema, and death of infected sheep and goats, mainly during summer in warm, humid climates. [2] Females may lay over 10,000 eggs a day, [3] which pass from the host animal in the faeces. After hatching from their eggs, H. contortus larvae molt several times, resulting in an L3 form that is infectious ...
The disease is endemic in the Indian subcontinent and is a major threat to fast-growing goat husbandry in India, causing an annual loss of around 1800 million Indian rupees. In North Africa , only Egypt was once hit, but since summer 2008, Morocco is suffering a generalized outbreak with 133 known cases in 129 provinces , mostly affecting sheep ...
